(E85: 85% ethanol)

More than 1,300 gas stations sell E85.
E85 pumps cost as much as $200,000.

15 to 32 mpg
(B20: 20% biodiesel)

Now 651 biodiesel stations. 100% BD requires engine conversion.

24 to 36 miles per gge

1,500+ NG fueling stations. 300,000 miles of pipelines.

14 to 67 miles per gge

Building enough stations for 1% of Americans to drive hydrogen cars would cost $472 million.

*gge = gasoline gallon equivalent. Average nationwide fuel costs as of 10/07 (biodiesel), 1/08 (natural gas), 3/08 (all others).

Where to begin?

79%

By 2009, new "clean diesel" vehicles will meet gasoline pollution standards.

75%

Coming soon: plug-ins that lower CO₂ emissions on routine commutes

26%

Most models go no more than 100 miles on a charge. Batteries still clunky.

28 to 193%

Corn ethanol may emit 500% more greenhouse gases than gasoline if grown on land that once absorbed CO₂.

70 to 150%

Burning down a rainforest to produce palm biodiesel is a bad idea—who knew?

70%

Only one model on the market. NG is cheap and abundant, but a fossil fuel.

42 to 67%

Current models cost $1 million. A car with a 300-mile range would need a trunk-size fuel tank.
